Republican National Committee Chairman Reince Priebus on Tuesday predicted the 2014 midterms would be a “tsunami” victory for the GOP, and pointed to young people and women as two groups with whom his party hopes to gain ground.

His comments came at a breakfast sponsored by the Christian Science Monitor as Republicans mark the one-year anniversary of their Growth and Opportunity Project report, an “autopsy” conducted to determine how the party stumbled in 2012.

“I think we’re in for a tsunami-type election in 2014,” Priebus said.”My belief is, it’s going to be a very big win, especially at the U.S. Senate level, and we may add some seats in congressional races. But I need to and we need to, at the RNC, make sure that we can capture the positives and the benefits we’ve been able to provide in 2014 and build on that to have success in 2016, which is a very different type of election.”

He was bullish on the Senate, where Republicans need to net six seats to regain control. He pointed to red states where Democrats are seeking reelection, noting that in many of those places, President Barack Obama is deeply unpopular, and argued that the health care act is “total poison across the country.”

Since last year’s report, the RNC also has tried to improve the party’s showings with groups including minorities, young people and women —all demographics with which the GOP stumbled significantly in 2012.

As he has argued before, he continued: “Then young people, Obamacare is intentionally designed to screw young people over. Actuaries sat down, decided, let’s just screw over everyone 35 and younger. That’s what they did.”

He acknowledged that the party has “some demographic challenges” and pledged that Republicans will “work like dogs to try to figure it out,” especially focusing on outreach to Asian, African American and Hispanic voters.

Democrats have argued that simply showing up to those communities isn’t sufficient; that the problem is with GOP policies. Shortly after the Monitor breakfast, the Democratic National Committee hosted a press conference of its own and released a report titled, “One year later, same old party.”

“The biggest problem for the Republican Party … is who they are, what they believe, what they say, and how they govern,” the DNC report charged.

Democrats, Priebus insisted at the breakfast, “have demographic challenges too. But for whatever reason, we seem to be obsessed with our own.”

Priebus was asked repeatedly, however, about comprehensive immigration reform — something the autopsy report strongly endorsed, but which has met stiff opposition from some in the GOP. He argued that an ideologically wide range of Republicans support some measure of change to the immigration system, even if not everyone agrees on details.

“I would … caution you not to impose your definition of what comprehensive immigration reform is,” he told one reporter at the breakfast. “There’s a general agreement that we need to have serious immigration reform, but I don’t believe there’s general agreement as to what that reform is.”
